Browser-based proactive secret sharing demo — Herzberg-Jarecki-Krawczyk-Yung 1995. A threshold scheme stops an attacker who takes t shares at once, not one who takes them slowly. Reshare and every old share becomes garbage while the secret stays byte-identical. Real Shamir over GF(p) with Feldman commitments. No backends. No simulated math.

Browser-based Feldman VSS and Pedersen VSS demo — verifiable secret sharing with live cheating dealer detection, commitment verification, and the layer beneath FROST and threshold wallets.

Browser-based distributed key generation demo — Pedersen/GJKR 1999. Build a group public key with no dealer, verify every share against Feldman commitments, then send one bad share and watch the public complaint round disqualify the dealer. Real secp256k1 arithmetic. No backend.
